"How is my life going and yours?"
Here's a breakdown:
* Vai bem: This is a common expression in Portuguese meaning "going well" or "doing well."
* Minha vida: This translates to "my life."
* E a tua: This means "and yours" (literally "and your").
* Como: This is the word for "how" in Portuguese.
So, the entire phrase is a casual way to ask someone how their life is going, implying that you're also interested in their well-being.
